Research ArticleOpen accessIn the abstractH-RABIN CRYPTOSYSTEMHayder Raheem HashimCryptography is the science of using mathematics that's used to hide information or data that is being sent between participants in a way that prevents other people from reading it. The need of exchanging messages secretly promoted the creation of cryptosystems to enable receivers to interpret the exchanged information. In this study, a particular public key cryptosystem called Rabin Cryptosystem … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 10 May 2014 · 7,640 accessesView PDFCite
Research ArticleOpen accessIn the abstractA NOVEL APPROACH FOR INFORMATION SECURITY IN AD HOC NETWORKS THROUGH SECURE KEY MANAGEMENTS. Suma Christal Mary, M. PallikondaRajasekaran, Y. ChrisbinJeevaAd hoc networks provide flexible and adaptive networks with no fixed infrastructure and dynamic topology. Owe to the vulnerability nature of ad hoc network, there are lots of security threats that diminish the development of ad hoc networks. Therefore, to provide security for information of users and to preserve their privacy, it becomes mandatory to use cryptographic techniques to set … …Journal of Computer Science, Vol. 9, Issue 11 · 2 Oct 2013 · 6,690 accessesView PDFCite
Research ArticleOpen accessIn the abstractMESSAGE AUTHENTICATION CODE BASED SECURE GROUP KEY MANAGEMENT PROTOCOL FOR MOBILE AD HOC NETWORKST. Peer Meera Labbai, V. RajamaniA mobile ad hoc network is a group of nodes which are communicating with each other with the use of radio frequencies. When there is high movement of mobile nodes, the nodes find difficult to reach other nodes. If the data are exchanged between nodes when there is high mobility, the data may be lost in transit. Therefore the security … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,727 accessesView PDFCite
Research ArticleOpen accessIn the abstractTemporal, Delegable and Cheap Update Access Control to Published XML DocumentsWaleed Halboob, Ali Mamat, Ramlan Mahmod, Muhammad Khurram KhanProviding access control for published XML documents on the Web is an important topic. It involves the use of cryptographic techniques, addressing different requirements and, as a result, facing several challenges. Existing solutions still have some weaknesses such as system update cost, number of required secret encryption/decryption keys, size of encrypted document and supporting temporal and delegable access. This study … …Journal of Computer Science, Vol. 9, Issue 4 · 8 May 2013 · 6,532 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Chaotic Encryption TechniqueAncy Mariam Babu, K. John SinghDrastic growth in multimedia communication resulted to numerous security issues in the transmission of data. Moreover, the network used for the digital communication does not provide much security for the data transfer. During this time, tens of millions people using the internet options for essential communication and is being a tool for commercial field increased, So that security is an … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 8 Jan 2013 · 7,206 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a New Elliptic Curve Cryptosystem with Factoring ProblemE. S. Ismail, M. S. HijaziProblem statement: The security of elliptic curve cryptosystems are based on elliptic curve discrete logarithm problem (ECDLP). However, if an attacker finds a solution to ECDLP, the elliptic curve-based systems will no longer be secure. Approach: To improve this, we develop a new elliptic curve cryptosystem using one of the old/novel problem in computational number theory; factoring problem (FAC). Specifically, … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 2 Aug 2012 · 6,788 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Star Topology based Multicast Key Management AlgorithmK. Saravanan, T. PurusothamanProblem statement: Secure group communication is very important for many applications such as internet pay sites. It provides efficient delivery of identical data to only the customers in the group. In large and dynamic multicast groups, the group keys of members have to be changed frequently whenever the member leaves or joins. A common method is to apply a symmetric … …Journal of Computer Science, Vol. 8, Issue 6 · 22 Mar 2012 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Mersenne Number Transform Diffusion Power AnalysisM. F. Al-Gailani, S. BoussaktaProblem statement: Due to significant developments in the processing power and parallel processing technologies, the existing encryption algorithms are increasingly susceptible to attacks, such as side-channel attacks, for example. Designing new encryption algorithms that work efficiently on different platforms and security levels to protect the transmitted data from any possible attacks is one of the most important issues in today’s … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 7,448 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecure Hybrid Mode-Based CryptosystemE. S. Ismail, S. BaharudinProblem statement: A cryptosystem provides two parties; a sender and a receiver to communicate interactively via an insecure channel in which, the sender is able to send any confidential message, document or data in a disguised form to the intended receiver. Upon receiving the disguised message, the receiver converts it to the intelligible message using his secret key. The security … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 12 Jan 2012 · 7,003 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Cryptosystem Using Multiple Cryptographic AssumptionsE. S. Ismail, M. S. HijaziProblem statement: A cryptosystem is a way for a sender and a receiver to communicate digitally by which the sender can send receiver any confidential or private message by first encrypting it using the receiver’s public key. Upon receiving the encrypted message, the receiver can confirm the originality of the message’s contents using his own secret key.
